“Where did you get that idea?”

Dale’s jaw set. “I won’t tell you.”

“What had the blue-prints to do with it?”

“Because I’d heard there was a Hidden Room in this house.”

The detective leaned forward intently. “Did you locate that room?”

Dale hesitated. “No.”

“Then why did you burn the blue-prints?”

Dale’s nerve was crumbling—breaking—under the repeated, monotonous impact of his questions.
